The "autoimmune/inflammatory syndrome induced by adjuvants" (ASIA) after COVID-19 infection: A case report.

The term "autoimmune/inflammatory syndrome induced by adjuvants" (ASIA) describes a variety of autoimmune conditions triggered by exposure to substances with adjuvant activity. We present the case of a patient with a history of biopolymer infiltration in both glutes, who years later experienced progressive weakness and pain in the lower limbs, myalgias, cramps, and progressive functional impotence following a mild COVID-19 infection. Laboratory test results were not consistent with any autoimmune disease. Physical examination revealed diffuse bilateral subcutaneous nodules. After an extensive etiological study, a gluteal biopsy was performed, which showed findings compatible with sclerosing lipogranuloma. Our patient required treatment with high-dose glucocorticoids and showed significant improvement in symptoms during long-term follow-up. We suggest the role of COVID-19 infection as a possible trigger for ASIA, as it has already been described as a trigger for several other autoimmune diseases.

El término «síndrome autoinmune/inflamatorio inducido por adyuvantes» (ASIA) describe una variedad de condiciones autoinmunes desencadenadas por la exposición a sustancias con actividad adyuvante. Presentamos el caso de una paciente con antecedentes de infiltración de biopolímeros en ambos glúteos que años más tarde experimentó debilidad progresiva y dolor en extremidades inferiores, mialgias, calambres e impotencia funcional progresiva después de una infección leve por COVID-19. Los resultados de los análisis de laboratorio no sugerían enfermedad autoinmune. El examen físico reveló nódulos subcutáneos difusos bilaterales. Después de un extenso estudio etiológico, se realizó una biopsia glútea, la cual mostró hallazgos compatibles con lipogranuloma esclerosante. La paciente requirió tratamiento con glucocorticoides a dosis altas y mostró una mejora significativa en los síntomas durante el seguimiento a largo plazo. Sugerimos el papel de la infección por COVID-19 como posible desencadenante de ASIA, ya que se ha descrito como desencadenante de otras enfermedades autoinmunes.(AU)

Mpox: Clinical Outcomes and Impact of Vaccination in People with and without HIV: A Population-Wide Study.

We investigated differences in mpox clinical outcomes in people with HIV (PWH) and without HIV (PWoH) and the impact of vaccination in Catalonia, Spain. We used surveillance data and the PISCIS HIV cohort. We included all confirmed mpox cases (May-December 2022). Of 2122 mpox cases, the majority had mild disease, 56% were Spanish, and 24% were from Latin America. A total of 40% were PWH, with a median CD4+T-cell of 715 cells/µL; 83% had HIV-RNA < 50 copies/mL; and 1.8% CD4+T-cell < 200 cells/µL. PWH had no increased risk for complications, except those with CD4+T-cell < 200 cells/µL. PWH with CD4+T-cell < 200 cells/µL were more likely to be from Latin America, had more generalized exanthema, and required hospitalization more frequently (p = 0.001). Diagnosis of other sexually transmitted infections (STIs) was common, both at mpox diagnosis (17%) and two years before (43%). Dose-sparing smallpox intradermal vaccination was accompanied by a sharp decrease in mpox incidence in both populations (p < 0.0001). In conclusion, unless immunosuppressed, PWH were not at increased risk of severe disease or hospitalization. Mpox is a marker of high-risk sexual behavior and was associated with high HIV and STI rates, supporting the need for screening in all mpox cases. Ethnicity disparities demonstrate the need for interventions to ensure equitable healthcare access. Dose-sparing smallpox vaccination retained effectiveness.

Similar CD4/CD8 Ratio Recovery After Initiation of Dolutegravir Plus Lamivudine Versus Dolutegravir or Bictegravir-Based Three-Drug Regimens in Naive Adults With HIV.

Background: The initiation of antiretroviral treatment based on a 2-drug regimen (2DR) with dolutegravir plus lamivudine has demonstrated non-inferior efficacy than dolutegravir-based three-drug regimens (3DR). We aimed to assess whether the treatment initiation with this 2DR has a different impact on the CD4/CD8 ratio recovery than INSTI-based 3DR. Methods: We emulated a target trial using observational data from the Spanish HIV Research Network cohort (CoRIS). The outcomes of interest were the normalization of the CD4/CD8 ratio at 48 weeks using three different cutoffs: 0.5, 1.0, and 1.5. We matched each participant who started 2DR with up to four participants who received 3DR. Subsequently, we fitted generalized estimating equation (GEE) models and used the Kaplan-Meier method for survival curves. Results: We included 485, 805, and 924 participants for cutoffs of 0.5, 1.0, and 1.5, respectively. At 48 weeks, 45% of participants achieved a CD4/CD8 ratio >0.5, 15% achieved a ratio >1.0, and 6% achieved a ratio >1.5. GEE models yielded a similar risk of reaching a CD4/CD8 ratio >0.5 (OR 1.00, 95% CI 0.67 - 1.50), CD4/CD8 >1.0 (OR 1.03, 95% CI 0.68 - 1.58), and CD4/CD8 >1.5 (OR 0.86, 95% CI 0.48 - 1.54) between both treatment strategies. There were no differences between 2DR and 3DR in the incidence ratio of CD4/CD8 ratio normalization at 0.5, 1.0 and 1.5 cut-offs. Conclusions: In this large cohort study in people with HIV, ART initiation with dolutegravir plus lamivudine vs. dolutegravir or bictegravir-based triple antiretroviral therapy showed no difference in the rates of CD4/CD8 normalization at 48 weeks.
